New Situation

Dengue is the world’s rapidly transmitting mosquito-borne viral disease. It is mostly found in subtropical countries in the world. The annual number of global deaths caused by dengue fever is about 25,000. The Sri Lanka dengue situation is also not different to other countries. In the year 2019, dengue fever caused 120 deaths in Sri Lanka. Most of these deaths were reported from the main administrative district Colombo. Health authorities have to pay their attention to control this new situation. Therefore, identifying the hot spots in the country and implementing necessary actions to control the disease is an important task. This study aims to develop a clustering technique to identify the dengue hot spots in Sri Lanka. Suitable risk factors are identified using expert ideas and reviewing available literature. The weights are derived using Chang’s extent method. These weights are used to prioritize the factors associated with dengue. Using the geometric mean, the interaction between the triggering variable and other variables is calculated. According to the interaction matrices, five dengue risk clusters are identified. It is found that high population movement in the area plays a dominant role to transmit the disease to other areas. Most of the districts in Sri Lanka will reach to moderate risk cluster in the year 2022.

Background Dengue is a mosquito-borne viral disease that has increasingly affected Sri Lanka in recent years. To address this issue, dengue surveillance through increasingly prevalent digital surveillance applications has been suggested for use by health authorities and the general public. Epihack Sri Lanka was a 5-day hackathon event organized to develop a digital dengue surveillance tool. Objective The goal of the research was to examine the effectiveness of a collaborative hackathon that brought together information technology (IT) and health experts from around the globe to develop a solution to the dengue pandemic in Sri Lanka. Methods Ethnographic observation and qualitative informal interviews were conducted with 58 attendees from 11 countries over the 5-day Epihack to identify the main factors that influence a collaborative hackathon. Interviews were transcribed and coded based on grounded theory. Results Three major themes were identified during the Epihack Sri Lanka event: engagement, communication, and current disease environment. Unlike other hackathons, Epihack had no winners or prizes and was collaborative rather than competitive, which worked well in formulating a variety of ideas and bringing together volunteers with a sense of civic duty to improve public health. Having health and IT experts work together concurrently was received positively and considered highly beneficial to the development of the product. Participants were overall very satisfied with the event, although they thought it could have been longer. Communication issues and cultural differences were observed but continued to decrease as the event progressed. This was found to be extremely important to the efficiency of the event, which highlighted the benefit of team-bonding exercises. Bringing expert knowledge and examples of systems from around the world benefited the creation of new ideas. However, developing a system that can adapt and cater to the local disease environment is important in successfully developing the concepts. Conclusions Epihack Sri Lanka was successful in bringing together health and IT experts to develop a digital solution for dengue surveillance. The collaborative format achieved a variety of fruitful ideas and may lead to more hackathons working in this way in the future. Good communication, participant engagement, and stakeholder interest with adaptation of ideas to complement the current environment are vital to achieve the goals of the event.

Abstract Covid-19 is a viral disease which has briskly invaded the globe, Sri Lanka being no exception. If community transmission of Covid-19 occurs, it will have serious demands on Sri Lanka’s free health care system. Objective of this study was to simulate the widespread community transmission of Covid-19 in Sri Lanka. We used the Susceptibility, Infected and Removed (SIR) model through the Penn State University CHIME Model incorporated to ArcGIS Pro. We simulated introduction of one case of Covid-19 to each of the 26 health districts and ran the model for 365 days. During simulated scenario, the number patients requiring admissions, ICU care and mechanical ventilation will peak at 1942, 583 and 388 per day respectively around 213 days from the onset of widespread community transmission. The cumulative number of cases needing admission, ICU care and ventilation will be 245,916, 73,775 and 49,183 after 365 days. Colombo and Gampaha districts will report the highest number of daily total numbers of hospitalized cases, each which will be over 1680. Health authorities must be ready for the worst-case scenarios of the Covid-19 outbreak to sustain public health response to reduce morbidity and mortality.

Dengue is a vector-borne viral disease. It is a disease caused by any one of the four closely related viruses (DEN-1, DEN-2, DEN-3, or DEN-4). The viruses are transmitted to humans by the bite of an infected mosquito (Aedes aegypti). Recently, there is an increase in the incidence of dengue fever in adult population in South Asian countries. With an increasing rate of adult dengue fever victims, the number of pregnant women infected with dengue has also increased. Dengue, during pregnancy may be associated with various complications, including abortions, preterm delivery, maternal mortality, low birth weight, neonatal admissions, and fetal anomalies. Timely intervention can improve the maternal as well as fetal outcome. This study was aimed to assess the clinical prole, maternal and fetal outcome of dengue fever during pregnancy and post-delivery. This study shows various outcomes in different trimesters of pregnanc

Abstract Dengue is a viral disease which is serious health concern from last few decades and the infection transmitted through mosquito bite into human. This study was conducted to carry out prevalence of dengue fever in District Swabi. A total of 196 blood sample were collected from patients with age ranges (0-80 years) having dengue fever on the basis of physical symptoms from Bacha Khan Medical Complex Swabi during August to October 2017. Serological test were performed for detection of IgM, IgG and NS1 (Non structural protein antigen of virus) against dengue. Out of total 196 confirmed dengue cases the most prone gender was male 123(62%) while 73(38%) were female. Among the age groups; 21-30 years group 62 (31.6%) was found the most predominated age group. The higly affected areas in district Swabi were Topi (40.8%) followed by Main Swabi (27%), Maneri (8.2%), Marghuz (6%), Shawa Ada (5.1%), Shah Mansoor (5.1%), Gohati (4.1%), and Chota Lahore (3.6%). Therefore, the health department should take actions by educating the public about basic cleanliness of the environment. The community should be encouraged to participate in the control of such vector based diseases/infections.

Background: Dengue fever is the most rapidly spreading mosquito-borne viral disease in the world.Incidence has increased 230-fold with increasing geographic expansion with potential for further spread. The rapidly expanding global footprint of dengue is a public health challenge with an economic burden. This study’s objective is to assess the outbreak of epidemic of dengue fever in a tertiary care children hospital and to describe their socio-demographic, clinical outcome and serological profile.Methods: It is an observational descriptive study conducted for a period of 1 year in less than 12 years old children in a tertiary care hospital at Southern Tamil Nadu.Results: Among the 360 children admitted with dengue fever, there were 198 boys (55%) and 162 (45%) were girls. Maximum incidence of dengue incidence was seen in infants less than 1 year (25%). The highest number of cases were admitted during September and October. The most common affected age group was less than 3 years with 179 (49%). Among the cases, 297 (82%) were of severe dengue which constitute dengue haemorrhagic fever-183(38%) and Dengue shock syndrome 114 (62%). Serological analysis showed NS1 Ag was positive in 144 children (40%), Dengue IgM was positive in 54 children (15%), both IgM and IgG positive in 126 children (35%) and IgG was positive in 36 children (10%). Out of the total children admitted with dengue fever, the case fatality was 0.5% (2 children).Conclusions: This study highlights the importance of WHO clinical criteria for early diagnosis of severe dengue. Moreover, the early and intensive management reduces the mortality significantly.
